Middle of the Linked List

Explore how to identify the middle node of a singly linked list by applying the fast and slow pointer technique. Understand the problem constraints and practice implementing a solution that handles both odd and even length lists in a hands-on environment.

We'll cover the following...

Statement

Given the head of a singly linked list, return the middle node of the linked list. If the number of nodes in the linked list is even, there will be two middle nodes, so return the second one.

Constraints:

Let n be the number of nodes in a linked list.

  • 1≤1 \leq
